How it works:
The MYO-Size Stack is an extremely powerful stack for researchers looking to put on massive amounts of muscle within a short period of time. With a 90 to 1 anabolic to androgenic ratio that does not aromatize into estrogen, RAD-140 is perfect for major lean muscle gains and strength gains whilst YK-11 inhibits the production of Myostatin in muscles by attaching itself to the androgen receptor. This induces muscles to create more Follistatin which in turn allows the research subjects muscle to grow beyond normal genetic capability.
